John Duncan MacFarlane (July 27, 1892 – December 8, 1982[1]) was a Scottish-born farmer and political figure in Saskatchewan.
In 1910, MacFarlane came to Canada, where he worked on farms and eventually earned his engineer's certificate.
After the war, he worked for the Soldier Settlement Board for three years.
MacFarlane then settled on a farm near Carlea, Saskatchewan, where he raised Clydesdale horses, Shorthorn cattle, Yorkshire pigs, Shropshire sheep and Barred Rock chickens.
[1] MacFarlane was defeated by Oakland Woods Valleau when he ran for reelection in 1938.
